What you can do

• Build your own workout by hand: pick a zone, add bodyweight exercises from a searchable library, set sets/reps/rest.
• Auto-fill a routine in one tap from a zone, time budget and level — then edit anything.
• Reuse saved workouts: load a past routine back into the builder and tweak it.
• Train with a guided session player — timer, rest countdown, exercise demo, and on-screen wake-lock so the screen never sleeps mid-set.
• Log the reps you actually did, then track progress: current streak, totals, and a per-exercise rep-evolution chart.
• Optional AI assistant (Gemini): bring your own API key to swap an exercise or make a workout easier/harder. Hidden entirely without a key — nothing else needs the network.
• Available in 6 languages: English, Spanish, Basque, Galician, Catalan and Valencian (auto-detected, switchable in Settings).
• Works offline after first load. Install it as a PWA on your phone.
• Local-only data, stored on your device. No signup, no email, no backend.

How to start

1. Open Ekin on your phone.
2. Name your workout, pick a zone, and add a few exercises.
3. Tap Start and train.
